Design of a cast bar reinforced provisional restoration for the management of the interim phase in implant dentistry.
(1/18)
Implant therapy is becoming the treatment of choice for the replacement of teeth in partially edentulous arches. The interim phase of implant treatment often presents particular problems because of the position of the remaining teeth, their periodontal status, and the loss of vertical dimension of occlusion. This case report will discuss the design and fabrication of a cast bar reinforced long-span provisional restoration based on a diagnostic wax-up to simplify the management of the interim phase.

In vitro comparison of peak polymerization temperatures of 5 provisional restoration resins.
(2/18)
BACKGROUND: The heat produced by provisional restoration materials may injure the dental pulp. This study measured and compared peak temperatures during polymerization of 5 materials used in the fabrication of provisional restorations. METHODS: The tested materials were 2 self-curing resins (Integrity and Protemp) and 3 dual-cure resins (Iso-Temp, TCB Dual Cure and Provipont DC). A mould the size of a maxillary molar tooth was fabricated to contain 0.5 cc of resin. The temperature rise of the different materials was recorded every 10 seconds over a 10-minute period. RESULTS: The rise in temperature of Integrity (peak temperature of 33.8 degrees C) and Protemp Garant (35.6 degrees C) was significantly higher than the rise in temperature of Iso-Temp (29.5 degrees C), TCB Dual Cure (28.4 degrees C) and Provipont DC (29.5 degrees C). CONCLUSION: Use of the dual-cure resins in provisional restorations may reduce the risk of pulp injury. (+info)

Occlusal stability in implant prosthodontics -- clinical factors to consider before implant placement.
(5/18)
The success of any prosthetic design depends on proper management of the occlusion. The clinical variables influencing occlusal stability must be determined and considered in the design of the final prosthesis. This paper outlines some of these variables. (+info)
A modified impression technique for accurate registration of peri-implant soft tissues.
(6/18)
Replacement of single missing teeth with an implant-supported restoration is recognized as a highly successful treatment. An impression technique for peri-implant soft-tissue replication in an anterior zone is described. The technique involves use of an interim restoration as an abutment for the final impression. This allows accurate duplication of the soft tissues and fabrication of a final restoration with the correct emergence profile. (+info)

The correlation of student performance in preclinical and clinical prosthodontic assessments.
(8/18)
Tracking student performance in preclinical and clinical courses can be helpful in developing and refining a curriculum. Our objective was to correlate student performance on three fixed prosthodontic examinations taken by eighty junior dental students. Examinations included a knowledge-based objective structured clinical examination (OSCE), a manual skills exercise completed on a typodont (Typodont), and a competency casting exam (Casting CE) on a patient. Multiple regression analysis indicated that the OSCE and Typodont exam scores, as independent variables, were not statistically significant predictors (P=0.07; P=0.87, respectively) of Casting CE exam performance, which was the dependent variable. Correlations were weak for the OSCE (r=0.21) and nearly nonexistent for the Typodont exam(r=0.03) when compared to the Casting CE. Our results indicate a weak correlation between an OSCE-based knowledge exam measuring students' knowledge of critical errors in preparations and castings and a competency exam involving the preparation of a full veneer crown. Results also indicate virtually no correlation between a typodont preparation examination designed to provide a measure of students' clinical skill and a clinical competency exam involving the preparation of a full crown.
